Robert Downey Jr. 'terrified' Tom Holland

ROBERT Downey Jr. "terrified" Tom Holland.

The 19-year-old actor - who is making his Marvel debut as Spider-Man in 'Captain America: Civil War' - admits he was initially nervous to work alongside the 51-year-old star but says he had no need to be as he welcomed him with open arms.

Speaking to BANG Showbiz at the UK premiere of 'Captain America: Civil War' on Tuesday evening (26.04.16), he said: "He is so cool. Robert Downey Jr is awesome. I first met him at my first screen test and obviously I thought Robert was terrifying but once I met him, he was down to earth, really cool and easy going.

"We got on really well and we work very well together. I'm just so happy these guys gave me the opportunity."

And Tom admits he is still in awe of everything that has happened to him so far and says it is a "dream" to walk the red carpet in hometown of London.

He added: "The crazy thing is this is where I buy my clothes, and now here we are at the red carpet of 'Civil War', I could never have dreamed of being here. I am so happy this has happened ...

"I mean obviously yes, it was quite nerve wracking at first, but these guys are so welcoming and so cool that I immediately felt like I was at home and I was part of something really amazing."
